LIBRARY-TABLE.

To all whom it may concern:

Be it known that I, AUGUST ZWIESLER, a

citizen of the United States, residing at Daysame, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful im rovements in library tables.

he object of the invention is to increase the utility of such tables by providing therein, in addition to other convenient appliances, a slide which serves the purpose of a writing desk and which has the essential features hereinafter described and claimed. The features of the slide, are first, that the use of said slide for a writing desk will not cause any unsteadiness or tilting of the table, and will obviate the necessity of making the table unusually heavy or weighting it, and secondly, the sliding connections between the extension slide and the table are of such a character as to assist in firmly supporting the slide itself in an extended or serviceable osition. In extending the slide, the drawer eneath it is also drawn out a sufficient distance, approximately one-third of the depth of said drawer and it thus serves as a rest or support for the slide. The act of drawing out the slide also draws out the drawer to the extent indicated above. The extension slide and the drawer are essentially of a depth which is substantially equal to the depth of the table or rather the space below the top of the table; this space is wholly occupied when the drawer and the slide are moved in to their limit. This enables the extension slide to be drawn out the necessary distance to provide the necessary writing surface, and yet ermit said slide and the drawer to remain 'ar enough beneath the top of the table to avoid an undue amount of. leverage being given said slide when it is extended or withdrawn to a serviceable posi tion. The usual pressure upon the slide will 7 therefore, not be sufiicient to tilt the table or make it unsteady, as would be the case if the slide were extended to an extent that Specification of Letters Patent.

to the extreme front of the table. And further, the connecting devices between the extension slide and the table are of a character to permit an independent movement of the drawer in and on In the annexed drawin s, Figured, is a perspective view of a li rary table constructed in accordance with my improve- Inents. Fig; 2, is a sectional view on the line a a of Fig. 1. Fig. 3, is an enlarged perspective view of a portion of the slide and a portion of one of the division strips lying beneath the to of the table.

is a perspective view of the drawer removed.

In the following description, similar reference characters indicate corresponding parts.

The library tables to which my improvements are especially ada ted are of the rectangular variety and of t e usual sizes. Beneath the top 1 of the table there is referably a drawer 1 which is of a depth su stantially equal to the depth of the space below the to of the table. This drawer may be centra ly located or it may be located on one side of the table as shown in Fig. 1. In construction, the drawer is provided with a space or compartment which is between an outer and an inner side 19 19. This space or compartment is not intended as a receptacle, butits purpose will be presently defined.

In the event the drawer is located at one end of the table as shown, an additional drawer may be placed in the table, or the space may be utilized to rovide a series of compartments 2 fonthe ing ofpapers, and provided with a hinged cover '3. These are mere matters of choice, however, and do not enter into the essence of my improvements. Defining further, the essentials of the construction, they consist of an extension slide 4 which lies below the to of the table and above the drawer 1. T is slide like the drawer, is of a length or de th to occupy the entire depth of the, space be ow the top of the would bring the inner edge thereof adjacent .70 Fig. 4, is a sectional view on the line b l) of Fig. 1.

e seen that the leverage of the slide when so drawn out, is not so great as it would be if it were drawn out or extended to the full extent.

of its len th or depth. As a consequence, it does not ecome necessary to make the table unusually heavy or to weight it in order to prevent it from tilting or becoming unsteady when 'the extension slide is drawn out and is serving the pur ose of a writing desk. The ends of said sli e are provided with channels 5 which terminate a suitable distance in from the corners as shown at 6. The upper side of the slide has attached to it a transverse strip 14 which forms a stop by engaging a strip 18 secured at the front of the table and thus the slide is limited in its withdrawal movement. The slide has a suitable pocket 7 in which to place an ink well, and another cavity 8 in which may be laced a pen holder, etc.

Secured to t e lower side of the slide, below the o ening which provides the pocket 7 for the in well, is a hollow block 21. This block combines in forming said pocket and provides means on the slide for moving the drawer out as shown in Figs. 2 and 4. The hollow block 21 engages the front of the drawer and the slide and drawer are moved out of such positions together, the drawer a sufficient distance to provide a rest or support for the slide in addition to other supporting guides to be presently referred to. It will be understood, the engagement of the strips 14 and 18 limit the outward movement of both slide and drawer. The front of the hollow block 21 is provided .with a rubber bumper 23 to soften the contact between said block and the front of the drawer. In moving either the slide or the drawer independently of each other, the hollow block 21-either moves within or lies within the space in the drawer between the panels 11). It will be noted in Fig. 5, the back of the drawer at the end of the said space or compartment is cut out as at 20, in order to permit the drawer to be entirely removed without the back engaging the hollow block 21 in such movement. The bottom of said hollow block and the drawer are each provided with an opening 22 which 0 enings come into alinement when both s 1de and drawer are moved out as in Fig. 4.

' Through these openings a pencil or other inwhereby said sli strument may be inserted to remove the ink well for cleansing, etc. From the foregoing description, it will be seen that the slide is caught by the fingers of the hand engaging the recess 24 in the underside of said slide and near the front edge. The slide is drawn out and the hollow block engaging the front of the drawer, the latter is also drawn out until both slide and drawer are thus moved out to the positions shown. The greater portion of the drawer still remains under the table, and the slide approximately at the middle 6 is firmly supported.

Cooperating with the channels 5 ,in the slide, are supporting guides 9 consistin of two metallic angle plates whichhave t fleir u per ends rojecte'd into sahi channels.

ese guide p ates 9 are secured respectively to the end and intermediate table rails 10. The positions of said guide plates 9, are near the front end of the table rails so that in any positionof the slide 4, they will provide an efiicient support on each side thereof as well as guides for the movement of the slide.

It will be noted that the point of attachment of the guide plates 9 is below the slide and their points of engagement with the slide are intermediate the upper and lower sides or surfaces of said slide, to-witin the channels 5. Also cooperating with the slide is another series of supporting guides consisting of metallic angle plates 12, one on each side. These guide plates 12 are of a suitable form for attachment to the upper side of the slide in positions to permit of the vouter ends thereof extending into the guide channels 13 in the adjacent table rails 10. The channels 13, it will be observed, are near the upper edges of said table rails. The guide plates 12 are near the inner corners of the slide, so that when said slide is drawn out, the supporting guides 12 and 9 on each side are in proximity to each other, one above the other, and the slide is thus maintained at its inner end in a firm and level position from two points of each of the table rails, to-w1t from an upper and a lower point, or from the point of attachment of the guide plate 9, and the point of connection between the gulde plates 12 and the rails 10. The result is, as )efore stated, the slide is sup orted firmly in its extended position by bot the extended drawer and said metallic plates, and is permitted to be moved freely in and out.

Having described my invention, I claim: 1. In a library table, the combination with a drawer, of an extension slide above said drawer and movable independently thereof,

means for limiting the outward movement of said slide to prevent excessive "leverage thereof in using the same, rails at the .side edges of said slide, and su porting guide plates on the slide and rail and forming sliding connections between two points of the slide and the rails.

2. In a library table, the combination with a table having a drawer, and end and intermediate rails having longitudinal channels therein adjacent to the u per edges of said rails, supporting guide p ates attached to said rails elow the channels therein, and an extension slide mounted above the drawer and movable independently thereof, said slide having channels in its op osite edges adapted to receive the guide Iates of the rails, and guide plates attached to the upper side of said slide and entering the longitudinal channels in the rails, and means limiting the extension movement of the slide.

3. In a librar table, a table to a drawer, the length of w ich is substantiai ly equal to the depth of the table, a slide, the lengthof which 1s substantially equal to the length of the'drawer, means on the upper side of said slide to limit the outward movement thereof, means on the lower side of the slide to engage the front of the drawer in the outward movement of the slide andto cause an outward movement of said drawer to an extent to provide a rest for the slide when said slide is moved out, table rails inclosing opposite sides of the drawer and the slide, and guide plates secured to said table rails and to the adjacent sides of the slide, and adapted to guide said slide inits movements, andlto coolpgrate with the drawer in supporting said s 1 e.

4. The combination with a table, a drawer, I

having a length substantially equal to the depth of said table, a slide between the drawer and the table to p and of a length substantially equal to the ength'of the drawer, said slide having an opening therein, a hollow block below said opening and providing a pocket foran ink well, said block being adapted to engage the front of the drawer in the outward movement of said slide, whereby the drawer with the slide is moved a sufficient distance to provide a rest for the extended slide, and means at the side. edges of the slide for guiding the same in its movements.

5. The combination with a table having end and intermediate rails and a lon itudinal front strip below the top of the tab e, of a drawer having a length substantially equal to the depth of the table, said drawer having a space extending throughout the length thereof at one side and a portion of the back of said drawer being removed so that the said space or com artment is uninclosed at the rear end of t e drawer, a slide above the drawer and of a length substantially equal to the drawer, said slide'having longitudlnal channels in its side ed es and an opening therethrough, a hollow lock secured to the lower side of the slide below said 0 ening and rovidin a pocket fo1 an ink wel said holow bloc projectin the slide adapted toengagevthe front longi-v tudinal rail of the table to limit the outward movement of the slide and the drawer when the drawer is being moved by the slide.
